Can pregnant women eat midnight snacks the day before drinking sugar water?

Pregnant women sometimes need to drink a lot of sugar water, especially glucose water, when they have a physical examination. Generally, this is to check the glucose tolerance during pregnancy, which is a necessary test for pregnant women. It is okay to have a midnight snack, but try to avoid it before 10 o'clock. If you eat after 10 o'clock, it will affect the correctness and accuracy of the data. Therefore, try to have a midnight snack before 10 o'clock the day before the examination.

What is the test for pregnant women drinking sugar water?

Drinking sugar water before the examination is usually used to test the glucose tolerance of pregnant women. The test for glucose tolerance during pregnancy is a blood test. You cannot drink anything after 10 pm the night before the test. The next morning, two tubes of blood are drawn on an empty stomach, and then glucose water is drunk immediately. One hour after drinking the glucose water, the second blood test is done, and the third blood test is done one hour later. Before the three blood tests are completed, except for drinking glucose water after the first blood test, you cannot drink water or eat breakfast.

Precautions for glucose tolerance test in pregnant women

1. Eat normally 3 days before the test

In the 3 days before the examination, the carbohydrate intake (i.e. rice and pasta) should not be less than 150 grams. If the subjects deliberately reduce the amount of staple food, the test results will be inaccurate, leading to misdiagnosis.

2. Avoid strenuous exercise and keep your emotions stable

Normal physical activity should be performed 3 days before the test. However, strenuous exercise before the test can excite the sympathetic nerves and increase blood sugar. Infection, trauma, and drastic mood swings can all excite the sympathetic nerves and affect the results of glucose tolerance tests.

3. Be sure to eat on an empty stomach

When doing a glucose tolerance test, the expectant mother must fast for 8 to 14 hours to truly reflect the fasting blood sugar level. For example, if you are doing a glucose tolerance test at 8 o'clock in the morning, it is best not to eat anything after 10 o'clock the night before, but you can drink water.

I believe that after reading this article, all pregnant friends will be able to understand what kind of examination pregnant women are undergoing when they drink sugar water before the examination. Different examinations have their own precautions, and we should understand them clearly to avoid inaccurate test results, which would be very troublesome. If you don’t understand something, you should ask the doctor in time.
